GABLE-CLAMPING DEVICE.

Specification of Letters Patent.

. Patented June 3, 1919.-

Application filed December 8, 1917. I Serial No. 206,206.

To all whom it may concern.

Be it known that I, WALTER T. GODDARD, of Victor, in the county ofOntario and State of .New York, have invented certain new and usefulImprovements in CableClamping Devices; and I do hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of Afor its purpose to provide a structure which can be economicallymanufactured and possessing the necessary strength and stiffness towithstand the usual strains to which it may be subjected. Still afurther object of my improvement lies in adopting an arrangement whichpermits the device to be manufactured from sheet metal through a seriesof stamping operations. To these and other ends the invention consistsin certain improvements and combinationsof parts, all as will behereinafter more fully described,

the novel features being pointed out in the claims at the end of thespecification.

In the drawings:

Figure 1 is a side'elevation showing my invention applied in operativerelationship;

Fig. 2 is an enlarged side elevation of the clamping device;

Fig. 3 is a bottom plan View;

Fig. 4 is a vertical sectional view on line 4= -4t of Fig. 2; V

Fig. 5 is an end elevation, and

Fig. 6 is a plan view of the blank from which the clamp is formed.

Similar reference numerals in the several figures indicate the sameparts.

For a general understanding of the application of' the invention, it issufiicient to state that 1 designates an insulator support which issuitably attached to some'stationary element and suspended from thesupport is the clamping device to which is secured a conducting cable 2.v

I preferably employ a blank plate such as shown in Fig. 6, which issubjected to a series of stamping operations to obtain the form ofdevice which is indicated in the re maining figures. Referring to Fig.6, the portion 3 is bent outwardly along the dotted line 1, forming acurved flange 5 at the apex of the triangular opening of the plate orbody portion, Fig. 2, which affords a bearing for the suspension memberor support ing clevis 6. The portion 7 of the blank is bent outwardly toone side along the dotted line 8, affording a substantially flat flange9 which is provided with bolt openings 10 for a purpose that will appearpresently. The lower portion 11 of the blank is bent upwardly andoutwardly along the dotted line 8, alfording a second flange at the baseof the opening 12, extending in a direction opposite to that of the flatflange 9, -and is recessed or substantially Vshaped, afi'ording a seat13 for the conductor 2. The body portion of the plate and also theopening 12 therein are preferably of substantially triangular shape, andthe ends of the seat 13 ,are fiared downwardly at the portions ll,

so that if the conductor is broken on one side of the clamp, theremaining end willbe held by the clamp, which will swing partially aboutthe clevis 6, and the surface 14 will afford a bearing for that portionof the cable portion 17 overlies the flange 9 and has a curved extremity18 which engages the upper side of the conductor. The clamping memberalso preferably includes an integral lower portion 19 which may extendunderneath the flange 9 and abuts against the same when the parts are inclamping relationship. The clampingmember is held rigidly against theconductor and against the flange 9 by means of bolts passing throughopenings in the flange 9 and in the clamping member and held in place bythe nuts 20. The bolt heads 21 are preferably curved on their innerfaces and engage correspondingly curved surfaces on the clamping member17 in order to effect a tight engagement between the conductor and theclamping member, which latter is slightly resilient. When the nuts 20are tightened, the lower portion 19 is held against the flat flange 9,preventing the clamping member from tilting, and retaining the conductorrigidly in the seat of the clamp.

The structure is an exceedingl practical and eflicient one, andeconomica to manu' edge of the opening to provide a bearing for asuspension member, a clamp support cable.
